Application filed July 19, 1926, Serial No. 123,350, and in sweden June 10,1925. (abandoned) My invention refers to the undulating or waving of the hair and more especially to means whereby the hair can be formed into waveszin a particularly easy and efficient manner. v

In the apparatus according to the present invention spoon or cup-shaped moulds and covers of awell known kind are provided with or formed as electric heaters which may for instance have the form of a plate carrying the moulds and covers. in a preferred form of my invention the spoon or cup-shaped moulds mounted in parallel taper in the longitudinaldirection, and wider portions of even moulds alternate with narrower portions of uneven moulds and vice versa. v

In the drawings afiixed to this specification and forming part thereof apparatus embodying my invention are illustrated diagrammatically by way of example. in the drawings h H p Fig. 1 is a plan View,

Fig. 2 a front View, and n Fig. 3 a side elevation partly in section of the first modification, while Fig. 1 is a plan View,

Fig. 5 is a cross-section on the line 11-11 in Fig. 4E, and

Fig. 6 is a front elevation of the second modification.

Referring first to Figs. 1 to 3. three spoonshaped moulds 1 tapering in longitudinal direction are juxtaposed in such manner that the narrow end of the inner mould is enclosed between the broad ends of the outer moulds. Themouius 1 are preferably made of metal such as aluminum. 2 are metal strips supporting the moulds and 3 are hinges connecting the strips in an easily disengageable manner. a is a heat-insulating cover. for instance consisting of asbestos. secured on the bottom surface of the strips 9.. The outer edge; of the moulds 1 are irovided with teeth 5 forming combs which serve for facilitating the arranging and holding; in place of the hair. 6 are covers equalling the moulds in shape and arranged to be inserted in the moulds. These covers are formed as heating bodies.;electric heat resistances being mounted in the hollow of the covers, care being taken to preventthe temperature from exceeding 125 0.. thereby obviating all danger of thehair being which also forms the heating means.

burnt. Connecting terniinals '7 are mounted at the ends of the covers (3 for supplying the heating resistances with current. ers 6 are secured to the moulds 1 by resilient hooksB fixed to the covers 6 and adapted to embrace the rear edges of the moulds whenthe covers are inserted therein. At the front ends links 9 and 10 are provided, the links 9 being hinged to the moulds at 11, while the links 10 are acted uponby coil springs 12, so as to apply themselves onto the covers. Each link 10 has a'hole 13 adapted to embrace a knob let mounted on top of each cover 6,'which is thus fixed in position in its mould 1. Rings 15 mounted atthe ends of the links 10 serve for opening and closing them. p V

The operation of this device is as follows:

The apparatus is secured to the head by suitable means. for instance with the aid of straps 16, and thehair is arranged on top of and transversely to the moulds. The covers and heating bodies 6 are now placed in position in the moulds and are fixed th'erein by means of the hooks 8 and links 9 and 10, whereby the hair is retained betweenthe covers and moulds. Current is now supplied to the covers 6. The length of the period of heating depends from the desired degree of waving;

Referring now to Figs. 4 6, the moulds are mounted on a plate-shaped support 17 is a hollow plate-shaped metal case which can be gripped and held bymeans of a heat insulating grip 18 and 19 is an electric resistance element inserted in the case. Current is supplied to this element by means of a conductor 20 inserted in the grip or handle 18. On the plate 17 are mounted the cup or spoon-shapedmoulds 25, the form and arrangement of which is substantially the same as described with reference to Figs, U-shaped bearing supports 26 are mounted near either end of the plate 17, these supports carrying the narrow ends of shaping covers 27 fitting in the moulds. These covers 27 are hinged to the supports 26, which at the same time serve to limit the opening movement of the covers, as shown for instance in Fig. 5. At the broad ends of the covers 27 are mounted tongues 28 adapted to cooperate with rotatable hooks 29 mounted on the plate 17 for locking the The covcovers in position in the moulds and for forcing them onto the moulds With a certain pressure.

Near the outer side Walls of the outermost moulds are rockingly mounted rails 30, Which are held in their locking position shown in the drawing by hooks 31, Which Can be rotated. These rails serve for hold ing the hair between them and the side Walls of the outermost mould.

The operation of this apparatus is substantially the same as described With reference to Eigs. 13. The hair is placed across the parallel moulds 25 and the shaping covers 2'? are then inserted in the moulds and secured in position by means of the hooks 29. The rails 30 are then mounted in position as shown in the drawings and are secured in this position by means of the hooks 31. The apparatus is now ready for operation and the electric current can be supplied to the heating element 19.

In the modifications shown in the drawings the moulds are arranged in parallel to the handle or grip 18, but obviously the ar-' rangement can be such that the moulds are arranged at right angles to the handle.

The electric heating elements shown in the drawings can also be replaced by means for heatingthe moulds and covers by gas,

. spirit and the like, and the moulds themselves or parts thereof may be formed as heating elements. i

A hair undulating apparatus compris ing a plurality of cup-shaped moulds and inandrels of corresponding configuration adapted to be inserted in said moulds, said moulds and mandrels being reduced at one end and arranged with the large and small ends alternately at opposite sides of said apparatus, and independent heating means on each mandrel.
